The B2B SaaS AI visibility index: which brands ChatGPT, Claude, and Gemini actually recommend when buyers ask what software to buy.
Every month we put 312 brand-neutral buyer questions to the three major AI assistants, record every product they name in order, and publish the whole thing here, ungated. The July 2026 snapshot covers 39 software categories and 2,808 real answers. Nothing is modeled, estimated, or backfilled: months we did not measure do not exist in the charts.
Answers come straight from the models' production APIs, brands are extracted in the order the models name them, and every score traces back to a raw answer we archive verbatim. The full recipe, including the scoring formula and its limitations, is on the methodology page. The monthly editorial read of the data is The Thunderdome Report.
Thunderdome is built and operated by Malcolm Angus, a data product manager who writes about turning the data companies already have into compounding advantage. No vendor pays to be included, excluded, or ranked.
